春季新交易与可重试结合 [英] Spring new transaction combined with Retryable

问题描述

如果我有一个方法可以针对某个异常重试Spring，并且还具有Transactional（Requires_new），那么每次重试完成时，它会创建一个新事务还是使用现有事务？

If I have a method that has a Spring retryable for a certain exception, and also has a Transactional(Requires_new), every time the retry is done, will it create a new transaction or use the existing one?

即

@Retryable(maxAttempts = 5, backoff = @Backoff(delay = 250), include = {ActivitiOptimisticLockingException.class})
@Transactional(propagation = Propagation.REQUIRES_NEW)
public void setVariable(String processId, String variableName, String variableValue){
    engine.getRuntimeService().setVariable(processId, variableName, variableValue);
}

这里实际会发生什么？

推荐答案

每次都会创建新交易。
它与从spring上下文获取服务和调用方法N次相同。每个调用都会创建新的事务（使用您添加到服务或方法中的传播）。调用您的交易代理方法，将其称为代理，也重试该代理。另外，您的交易可能会超时，请在新的超时时间内重试尝试调用，而不是在一次超时中尝试N次

will be created new transaction each time. it the same as get service from spring context and call method N times. every call creates new transaction (use propagation that you added into service or method). Call your transactioanl servics method call it's call a proxy, retry calls that proxy also. Also your transaction might have timeout,retry try call in new timeout duration ,not N try times in one timeout
